This breaks down to "How to remove all (but one) spaces at the start of a string"?
Removing spaces is easy:
In [1]: " abcd".lstrip()
Out[1]: 'abcd'
Then, just add a space, so... " " + mystring.lstrip()
.
That's the building block. The next part of the question is: "How to apply this to all the keys?":
Abbr = [" " + s.lstrip() for s in Abbr]
Then build your dictionary.
